TOF Multiplicities

•The figures show the TOF multiplicities for wall TB and wall TC. The following requirements must be satisfied:

•A good pulse height in both top and bottom PMTs.

•A prompt time signals in both top and bottom PMTs.

•

•Observations are similar to those made by the SpecTrig group: the multiplicities for collision events (red) are much lower than the multiplicities for beam-gas events (blue).
